Add example project for creating a custom socket event source and a tutorial for using it

Description

Currently, there is only a mention of socket event sources in the configuration documentation, but no example code or tutorial for how to do it. Add an example project that shows how to parse custom data from sockets and create SiteWhere events. Add a tutorial that explains how the example project works and how to install it into an existing SiteWhere instance.
